Ukraine crisis: What would a new Cold War mean for the economy?

The prospect of a full-scale Russian invasion of Ukraine has prompted pessimistic talk of a new Cold War.

But what impact could a resurrected East-West stand-off have on the world economy? Global stock markets sold off heavily yesterday, implying investors believe the impact could be highly adverse.

America's S&P 500 retreated by 1 per cent. The FTSE 100 shed 1.49 per cent. Stock markets in Asia also fell. But the biggest shock was on Russia's RTS index of shares, which shed 12 per cent. If shareholders are correct, Russia will suffer most from this escalation.

Energy is a key sector. The region accounts for a quarter of the world's natural gas reserves. Conflict could halt exploration in Ukraine, which has ambitions to be an exporter by 2020. Chevron has a $400m (£240m) contract to tap Ukraine's Oleska shale gas fields. The company said yesterday it had stepped up security in response to the arrival of Russian troops in Crimea at the weekend.

Western energy firms are operating in Russia itself. Exxon and Shell have operations in the country which could be vulnerable if East-West relations collapse. They were both marked down on the US stock market yesterday. Shares in BP, which saw the value of its investment in the giant Russian oil producer Rosneft drop by $1bn yesterday, were also penalised.

Russia's own gas exports, which account for a fifth of the country's overseas sales, could also be interrupted if Moscow is hit by Western sanctions. Yet this is a sword that would cut both ways. Europe is heavily dependent on Russian energy supplies. Gazprom, as well as sponsoring the Uefa Champions League football tournament, provides an estimated 30 per cent of the Continent's natural gas; 40 per cent of Germany's consumption; and 27 per cent of Italy's. Europe also consumes a third of the 4.2 million barrels of crude oil pumped daily by Rosneft. A significant portion of those supplies arrive via pipelines that pass through the Ukraine.

This dependency probably explains why there seems to be reticence among European politicians – who are meeting to determine the EU's response – to discuss targeting Russian energy exports directly.

To say Russia has Europe over a barrel would be an exaggeration. But it would be difficult for Europe to source new supplies in a hurry if deliveries from the East were disrupted.

Energy is by no means the whole economic story. Since the collapse of the Soviet Union other Western firms have penetrated the markets of the former Communist territory. The German engineer Siemens had sales of $3bn in Russia in 2013. McDonald's has 350 restaurants in Russia and around 80 in Ukraine. Pepsi has $4.9bn of sales in Russia. Firms with exposure to the region were heavily beaten in the markets yesterday. Carlsberg, which owns Russia's biggest brewer, Baltika, fell 5.2 per cent. Stada Arzneimittel, Germany's largest generic drug maker, has a fifth of its sales in Russia. Stada's shares fell 5 per cent. Europe could impose sanctions on Russian financial institutions, although that too could backfire by hitting the Continent's banks. Analysts were poring over European banks' exposure to Ukraine and Russia yesterday. Hungary's OTP, Austria's Raiffeisen and France's Société Générale all have chunks of their assets in Russia.

Despite the uncertainty over the likelihood or the target of Western sanctions, currency markets are already reeling. Ukraine's hryvnia fell by around 12 per cent against the euro yesterday. The rouble has also dropped sharply since Russian troops entered the Crimean peninsula, falling to 36.5 against the dollar, its weakest on record. The Central Bank of Russia was forced to lift its benchmark interest rate by 1.5 percentage points to 7 per cent yesterday, to bolster confidence. It is rumoured to have sold more than $10bn of its dollar reserves to prop up the currency.

Commodities markets are also pricing in the threat of disruption to energy and agricultural supplies from the region. Commodity prices rose to the highest level in six month yesterday. Brent crude oil hit $111 a barrel, its highest level this year. Corn and wheat prices also jumped. Ukraine is a major grain exporter, ranking only behind the US in annual output by some estimates.

If conflict does break out, consumer prices around the world could be pushed up, delivering another unwelcome inflationary shock to a global economy that, in the eyes of many, had finally turned the page on the turmoil of the financial crisis.

Not only smaller Mujicule, but also bankrupt. Its stock market has collapsed this week and its currency tumbled to record lows. It won't be able to sustain this adventure for much longer. Yesterday Gazprom executives were in London calming shareholders as their stock price has practically collapsed and there are many angry investors.....

Same blah blah blah from South Ossetia conflict. No long term damage to Rus economy, west realize they need Russia, time moves on.

Georgia like EU report before them, blame their tie-eating president for starting the aggression, realize that their neighbor world's largest country = huge market and they are only hurting themselves by acting childish for cutting themselves off from it, now they trade once again with Russia n regain relations.

Western Ukraine is just another dimwit place ignoring reality, just wait until next winter he he he. Fools need to run into walls because they ignore the obvious in front of them...
